Shouldn't this be important instead? According to
https://release.debian.org/stretch/arch_qualify.html powerpc is not
a release candidate.
Of course, I am eager to find solution to the crash regardless, just
arguing about it affecting the potential migration of firebird3.0 to

Hmm. I have seen this on amd64 when gcc switched to version 6. Getting
it built required adding -std=gnu++98 -fno-lifetime-dse
-fno-delete-null-pointer-checks -fno-strict-aliasing to the compiler
flags. Probably unrelated.

This is interesting. I was trying to debug a similar issue today on
the mips64el porterbox. One of the command-line utilities of firebird
produces garbage upon exit breaking a database verification at the end
of the build process. (Build log:
There is random garbage emitted by the firebird source preprocessor
(gpre) which is visible earlier in the build log.
Alpha is also affected.

Where did you add that _IO_stdin_used entry? There are several *.vers
files in the source. I'll try with all of them and also
(15 minutes later) Oh, it helps! The invocations of gpre no longer
dump sources. Let's see how far this goes.
